Fixes prompt indicator in case if the repository requires a non-default
feature. With HGRCPATH, it results in:
abort: repository requires features unknown to this Mercurial: ...
(see https://mercurial-scm.org/wiki/MissingRequirement for more information)
Which, in turn, results in "default" getting reported regardless of what
is the current state of the repo.
Before this change, ${git_unapplied_s} was unused and the %c
(${hook_com[unapplied]}) expando evaluated to the number of digits in
the string returned by the gen-unapplied-string hook (or to the number
of digits in the number of unapplied patches, when there was no such
hook).
The parameter *is* being declared with the redefinition of the
function, but not in its initial form, which gets you a warning
about the parameter being defined globally. This fixes it.
This is related to 33405. Turns out that not all other calls to
VCS_INFO_set are okay: With recent zsh versions the early call to that
function with the '-preinit-' argument causes a warning like this:
VCS_INFO_set:9: math parameter maxexports created globally
in function VCS_INFO_set
This fixes it.
Mikael informs me on IRC, that in new versions of git (he used 2.6.1)
where the "am" subcommand is now a builtin, a file that is used by the
git backend of vcs_info (namely .git/rebase-apply/msg-clean) is not
available anymore, leading to an annoying error message:
VCS_INFO_get_data_git:232: no such file or directory: .git/rebase-apply/msg-clean
This patch checks for the availabiliy of the file before using it,
and adjusts the value of the dependant values accordingly.
Before this patch, $gitbranch would be set to empty, which caused
VCS_INFO_get_data_git to early out with a failure status¹, consequently
$vcs_info_msg_0_ would be empty.

This sets the %b expando to the hash of the before-the-merge HEAD, rather
than to the literal string "detached HEAD". That hash is already available
via the gen-applied-string hook.
When pressing Ctrl-C after `git am`, only `last` exists in
`.git/rebase-apply/`, which is empty.
This patch fixes it to fall back to "no patch applied" then.
This shows, during 'git merge', the revision hashes of the "remote" head
(the one that will become second parent of the commit) in the %m expando.

When running git rebase -m and a conflict occurs, the git-rebase-todo
file is not present. This leads to an error from grep every time the
shell prompt is printed when vcs_info is enabled. Avoid this message by
checking if the file exists before trying to grep it.
When patches are applied, let quilt use .pc without forcing the
patch directory, this will fix the unapplied detection when being in
subdir.
When no patches are applied, use zstyle quilt-patch-dir then
QUILT_PATCHES then "patches" for path to search for patches.
Note: prefer setting quilt-patch-dir rather than QUILT_PATCHES for
absolute path because when patches are applied, quilt unapplied will
not return the correct list (i.e. the whole list rather that the one
specified by .pc/.quilt_series).
