I was surprised and concerned to read that (how did I miss the
failing test?), until I found that I didn't have this test! (Phew)
I assume this is a post 1.4.1 test, and from the name, I suppose
they would have mostly failed for me anyway since I don't have
svn installed.
In any event, I'm sorry to have broken your test, I should have
documented the changed behaviour. The change should be limited to
a lower-case usage prefix and a change in exit code from 1 to 129.
The change from "Usage:" to "usage:" was for consistency with every
other command (ignoring the test-delta program). The exit code
change only applies to one of the four original cmd_usage() call
sites; namely the one changed to a usage() call. Hmmm, should
the other three "call sites" change to exit(129) as well?
Any other change in behavior was unintentional. Did I miss
something?
Speaking of consistency, I noticed some inconsistent command
names in various usage strings. I attach a patch (p0011.txt)
for your consideration.
During one of my "grep-fests", I also noticed some calls to
die(usage_string) rather than usage(usage_string). Calling die()
rather than usage() means that a "fatal: " (rather than "usage: ")
prefix is output prior the usage string, and the exit code
is 128 (rather than 129).
It looks like to choice of die() was deliberate, particularly in
builtin-rm.c and hash-object.c since they call both die() and
usage(). However, It's not clear to me why this choice was made.
(Which is not to say there isn't a perfectly good reason for the
choice; it's just that I don't see it.)
I attach a patch (p0012.txt) which replaces these calls to die()
with usage(). Since it is possible, however unlikely, that there
are some scripts out there that depend on the current behavior,
you may not want to apply it.
Cheers,
Ramsay

Subject: [PATCH] Fixup command names in some usage strings.
Most usage strings, such as for command xxx, start with "git-xxx".
This updates the rebels to conform to the general pattern.
(The git wrapper is an exception to this, of course ...)

Subject: [PATCH] Replace some calls to die(usage_str) with usage(usage_str).
The only change in behaviour should be having a "usage: " prefix
on the output string rather than "fatal: ", and an exit code of
129 rather than 128.
