tog: add C-g/backspace key map to abort compound cmds Problem reported by stsp: 9999j would tie up tog till completed. While here, trim trailing whitespace in tog.1 and make C-g alias existing backspace abort key map for search and G in log view. ok op@ and stsp@

tog: expand horizontal split support to all views With this, hsplits are now available to the same parent/child view combinations as vsplits. Includes OB1 log truncation fix from op@ that was reported by stsp. ok stsp@

tog: remove count prefix timeout and bold output Suggested by naddy. block till non-numeric input is entered, and don't echo in bold. ok naddy@ op@ and stsp@

unconditionally set x/y pointers in view_get_split() suggested by and ok op@

make the diff algorithm used by 'tog diff' and 'tog blame' configurable ok jamsek

switch 'tog diff' and 'tog blame' to Myers diff for speed Make the choice of diff algorithm configurable by diff API users. The got and gotweb programs keep using Patience diffs which are prettier than Myers. But tog should be as fast as possible since it is being used interactively. If performance of Patience diff gets improved later we can consider switching tog back over to it. ok tracey jamsek

tog: fix C-d and G log view keymaps in horizontal split Account for the border so we don't scroll offscreen, and don't unset the load_all flag till all commits have been loaded so we take the correct path in log_move_cursor_down(). ok stsp@

fix fullscreen / split-screen toggle in tog ok jamsek

move remaining got_opentemp's out of blame. ok op@

tog: implement support for horizontal splitscreens Enable all main views to open primary child views in a horizontal split: log -> diff tree -> blame blame -> diff ref -> log Support is yet to be expanded to nested child views and key maps for manipulating split type and size. ok op@ and stsp@

tog: refactor log cursor movement in prep for hsplit Simplify the log input handler by moving (page)up/down and home/end logic into helper routines as we need to perform some checks on these cases when navigating the log view in horizontal splits. ok op@ and stsp@

fix split-screen issue in tog when moving focus from child view to parent view Reported by jamsek: $ tog # term wide enough to vsplit return # open commit f # fullscreen commit tab # should go to fullscreen log, but it splits the screen fix ok jamsek

fix recent regression in tog where split view was not restored after resize ok jamesk

move got_opentempfd() out of lib/diff.c again ok tracey

move got_opentempfd out of blame_open ok stsp@ jrick@

move got_opentempfd out of open_blob. ok stsp@

tog: echo count prefix when entering compound key maps like less(1), echo the digits as they're typed. suggested by and ok op@ stsp@

always show commit or tree IDs in diff header, in order to help 'got patch' The idea is that got patch can simply look for a line such as: commit - abcde1234567... to find the merge base commit ID to show in diff3 conflict markers. got log -p now displays commit IDs in its diff header, instead ofl tree or blob IDs. ok op@

build with -Wmissing-prototypes ok stsp@

tog: prefix mvmt keymaps with count modifier like vi(1) Enable compound commands for all movement keymaps (e.g., hjkl, bfdu). The optional prefixed count determines how many times the movement is performed; for example, '123j' (move 123 lines down) or '4f' (scroll 4 pages down). Counts are ignored if preceding non-movement and some singular movement operations (e.g., 't', 'r', 'ret', '/', '$', 'G', 'g'). ok stsp@

fix `limit' accounting in draw_commit if the child view is fullscreen we don't need to subtract one, because no vborder is drawn. ok Mark Jamsek

tog: make SPACE page down in all views ok op@, Mark Jamsek

fix fullscreen view regression introduced in 0dbbbe90fd When cycling from a child view in fullscreen, the parent view is opened in a splitscreen with no border instead of fullscreen. Check the view mode when cycling between views and resize parent dimensions accordingly. ok op@

alias C-b/C-f to scroll page back/forward with b/f Suggested by naddy. Remap 'f'ullscreen to 'F', and blame view key maps 'b' and 'B' to 'c' and 'C', respectively, per stsp's and naddy's suggestion. While here, remove trailing whitespace. ok naddy@
