Prompted by a suggestion from stsp to make the help view distinct rather than follow the default behaviour of established views. Occupying the fullscreen seems to be a somewhat established convention for TUI apps. ok stsp@

Don't pass '-v' to the command buitin.

Replace with got_object_commit_retain() to increment commit object reference counter. suggested by and ok stsp@

Reported by stsp: Embedded utf8 precludes developers running C locales from browsing the code. Fix was suggested by stsp with hints from the tmux(1) codebase. ok stsp@

Suggested by stsp. While here, add declarations for new help view routines. ok stsp@

Original idea inspired from discussion with tb, tobhe, and stsp at g2k22: display view-specific help, with option to toggle display of full key map reference when {H,F1} is pressed again inside the help view. Includes improvements suggested by stsp. ok stsp@

libbsd as a library was created some years back to pull together BSD-specific functionality to be used on non-BSD systems. When it was in its infancy, and not being widely adopted across non-BSD systems, there was often a need to carry around compat versions of sys/{queue,tree}.h This is no longer the case -- and the compat code for this has never worked on systems which lacked a compatible sys/tree.h header anyway, so remove this, and let the user know that libbsd is needed. A few people have mentioned this to me.

When checking for GNU Bison (and presumably other) toolchain commands on MacOS, ther's two main systems most users use. Brew, and Ports. Both of these take different approaches when building software, and although a Portsfile exists for -portable now, those users who don't use that directly, or use brew, and try and build -portable from git directly, will likely be at the mercy of ./configure being able to go off and find the appropriate tools. Therefore, ./configure *tries* to be smart about handling this, and will go and check if brew(1) is installed and try and use that to determine the likely path for where it puts its software. Indeed, for MacPorts, the story is very different, and although some users might therfore use --prefix to ./configure to determine this path, there is an overloaded assumption between --prefix meaning where the binaries are to be installed, and --prefix meaning "go and look elsewhere for other applications". At some point, a dedicated configure option might be required. Reported by grey and jamsek.

Use the & key map to enter a pattern with which to limit the displayed commits to those matching the provided pattern; similar to less(1) and mutt's limit feature. Includes various tweaks from op. ok plus fixes from op@

and adjust the callers. discussed with and ok stsp@

Remove some unneeded comments which were references to files. Add a quick summary output at the end of ./configure which will aid with CI debugging.

When creating a release tarball, use a GOT_RELEASE variable to determine the version of the release.

When installing gotwebd, put this under ${prefix}/sbin

In splitscreen mode, make the active view headline highlight extend the full width of view->ncols. While here, format the tree view header like the blame view by moving the index to the path line. suggested by and ok stsp@
