Patch by jamsek with a request to commit. Thanks!

Aborting tog regress with Ctrl-C would trigger a "tty" pledge violation via the built-in ncurses handler for SIGINT, installed by newterm(). Install tog's own signal handlers earlier to fix this.

leftover from 79c49d8454.

This callback could return any error code. Do not mask all such errors as cancellation.

As reported by naddy, this is a non-portable Korn shell construct. Instead, use the one argument array then make faux space-delimited string "arrays" for the other ids; they can still be indexed with pop_idx. improved by + ok naddy@

Walking the whole file index can take some time. Avoid delaying the perceived start-up time of tog by reading the file index in the background log thread. Problem pointed out by op@ with fixes from + ok jamsek

The marker annotates the commit, so it makes more sense to visually tie it to the log message than the author. Patch by stsp, I just removed a block. ok stsp@

As suggested by stsp, show the out-of-date symbol for the work tree branch if it is not only out of date in relation to the branch tip but also if it contains mixed commits. Update regress and add new test to check for this case. Also, explain the mixed commit condition of * and ~ markers denoting work tree state in got(1) branch -l docs. ok stsp@

If tog is invoked in a work tree, prefix the base commit log message summary line with a '*' if the work tree is up-to-date, and with a '~' if the base commit is not up-to-date with respect to the branch tip or it contains mixed commits. While here, plug a couple worktree leaks in cmd_ref() and cmd_tree(). ok stsp@

Fixes occasional test failures. Patch by jamsek

Allow keywords as arguments to options and operands for the blame, diff, log, and tree commands. Also, return 1 when exiting tog with error rather than 0 so regress can discern success from failure. ok stsp@

This prevents mixing the use of got and cvg clients in the same work tree. Avoids confusion going forward while cvg differentiates itself further. tog(1) and gotadmin(1) remain compatible with both work tree formats. These tools only read work trees to locate the corresponding repository.
