const-ify command and option tables ok stsp

tweak error reporting due to invalid numbers Use the same idiom as in the strtonum(3) manpage which produces a more readable error message. OK kn, stsp

show rebase and histedit backups in tog ref view ok naddy

tog: clear search highlighting when reloading view Clear the search highlighting when replacing the content of a diff view ('<', '>', '[', ']', 'a', 'w') or a blame view ('b', 'p', 'B'). Previously the position would remain highlighted even if the text there had changed. ok stsp@ or a blame view

make tog searches start from the current position in all views ok naddy@

let new 'tog log' searches start out from the currently selected commit ok naddy tracey

switch tog ref view's sort order command key to "o" instead of "s" The letter "o" does not overlap with existing options of 'got ref' and is also used by mutt(1) for this purpose.

make tog use got_reflist_sort() instead of reloading refs while sorting them

allow sorting references by timestamp in tog

tog: add Ctrl-n/Ctrl-p shortcuts scrolling one line down/up; patch by Omar Polo

implement 'got diff -c' for diffing commits with optional filtering by path Need for filtering by path sugggested by kn@ ok naddy@

show parent commit IDs of merge commits in the tog diff view ok tracey

tog: use sched_yield(2) instead of pthread_yield(3) for portability pthread_yield(3) is an optional POSIX 2001 extension while sched_yield(2) is part of POSIX 2008. On OpenBSD they are actually equivalent, albeit not documented as such. Using sched_yield(2) helps the -portable version. Patch by Quentin Rameau

tog: document why _XOPEN_SOURCE_EXTENDED is set and don't undefine it

tog: when jumping to the bottom of the log view, go from the tail backwards ok jasper

tog: jump directly to first log item instead of traversing the list ok tracey

tog: add support for navigating to first/last line of tree and ref views ok stsp

tog: add support for navigating to first/last line of blame view ok tracey stsp

make tog block other keys except Backspace after End/G is pressed This should avoid unexpected behaviour resulting from unrelated key presses messing with the log view's state variables. Pointed out by tracey, and also discussed with jasper. ok tracey

remove the 'ctrl+u' shortcut in favor of just 'g' in the diff view, too

make tog ignore Ctrl+L and B while loading all commits Otherwise tog gets into a funky non-recoverable state if these keys are pressed instead of Backspace while commits are loading. bug found by + ok tracey

remove the 'ctrl+u' shortcut in favour of just 'g' as alias for 'Home' Our use of ctrl+u was not consistent with vi(1) after all. Discussed with naddy, tb, and jasper on gameoftrees@

Allow commit loading trigged by the End/G keys to be cancelled with Backspace. ok jasper

tog: add support for navigating to first/last item of log and diff views The keybindings that we settled on are Home, Ctrl-u and g to go to the first item and End, G to go to the last. This resembles those commonly found elsewhere, eg vi/less. discussed with and ok stsp

use gmtime_r(3) instead of localtime_r(3) to display time in UTC as intended Problem noticed by naddy due to failing regress tests at midnight, and then analyzed with additional help from millert. ok naddy
