In empty repositories, HEAD is an unresolvable symbolic ref. Start computing
stagedstr/unstagedstr in that case; for the former, use a different method
than the non-empty-repository case.
The previous code would fail to detect the wcroot with Subversion 1.7+
when cwd is at least two levels below the root (i.e., ../../.svn exists
and ../.svn doesn't), and would then pass to the hook the revision and
basename of cwd rather than of the wcroot.
Previously, the value of the wc root would be used. In Subversion,
it makes more sense to use the revision of cwd, since all commands
(e.g., 'svn ci', 'svnversion') operate only on cwd and below, not on
wcroot and below.
This makes %b expand to a refname rather than a sha1 when HEAD is detached but
happens to match some ref (branch, tag, etc). The resulting output will
typically contain a slash (e.g., "tags/v1.0.2", "heads/mybranch"), which helps
distinguish it from the output in the "HEAD is a symbolic ref" case.
Given `alias fetch='noglob fetch'`, without this change `run-help fetch`
recurses to invoke itself on the noglob command, bringing up the help
for noglob. Similarly for nocorrect. Thus the user would have to quit
out of the pager, then avoid quitting out of the loop, so that they can
go into the second iteration and see the help for the second instance
found by `whence -a`, which happens to be the target of the alias.
With common pagers, that's thus 'q', 'not-q'. Somewhat frustrating.
Without this change, `alias foo='noglob bar'` where `foo` is not
otherwise a command would _never_ show the help for `bar`, since it only
showed the help for `noglob` and there was no second line of whence
output to trigger the second pass.
With this change, aliases to `noglob|nocorrect` of a command somewhat
ignore the presence of that precommand modifier; if a command is aliased
to `noglob $itself`, then the result is that the first line of whence
output is shown, no pager is used, the user can immediately see a prompt
to continue and press something other-than-q to see the help for the
command.
If given `alias foo='noglob bar'` then `run-help foo` will immediately
show the help for bar.
This behaviour was chosen to be consistent with the existing alias
support, but just working better with the precommand modifier.
Guilt uses the same internal directory for keeping state as stgit, but
it doesn't use the same files (not surprisingly). This caused error
messages due to missing files.
This fixes that by making the "stgit-active?" test stricter.
