revset: add wdir() function to specify workingctx revision by command
The main purpose of wdir() is to annotate working-directory files.
Currently many commands and revsets cannot handle workingctx and may raise
exception. For example, -r ":wdir()" results in TypeError. This problem will
be addressed by future patches.
We could add "wdir" symbol instead, but it would conflict with the existing
tag, bookmark or branch. So I decided not to.
List of commands that will potentially support workingctx revision:
command default remarks
-------- ------- -----------------------------------------------------
annotate p1 useful
archive p1 might be useful
cat p1 might be useful on Windows (no cat)
diff p1:wdir (default)
export p1 might be useful if wctx can have draft commit message
files wdir (default)
grep tip:0 might be useful
identify wdir (default)
locate wdir (default)
log tip:0 might be useful with -p or -G option
parents wdir (default)
status wdir (default)
This patch includes minimal test of "hg status" that should be able to handle
the workingctx revision.
