[Quilt-dev] Bugfixes: "delete" call to "pop" has wrong target; QUILT_DELETE_ARGS inherited by "pop"

[Joe Green]

Hi,

I've found a couple of bugs in the delete command.

When deleting the top patch by calling "quilt delete" with no arguments, 
pop is called as "@QUILT@/pop -fq $patch".  This doesn't pop that patch, 
it pops *to* that patch, so the operation fails.  The "$patch" argument 
should be removed to pop the top patch.
Also, I have QUILT_DELETE_ARGS set to "-r --backup" in my .quiltrc, and 
these are passed on to "pop", which results in an error:
   getopt: invalid option -- r
   getopt: unrecognized option `--backup'
   Usage: quilt pop [-afRqv] [num|patch]

The first attached patch "quilt-delete_pop.patch" fixes these problems.

The second patch "quilt-quilt_command.patch" creates a patchfn 
"quilt_command()" which can be used to invoke subcommands.  I think it 
would be good to apply this patch as well for consistency in how 
subcommands are called.  One question on this patch is whether or not 
the QUILT_COMMAND variable should be set so that QUILT_*_ARGS are 
applied to the subcommands, or so that only the arguments passed in by 
the calling command are applied.  This version does the latter.

There are a number of problems with the way "quilt pop" is invoked from
"quilt delete":

  - Unlike the old rpatch function, "pop <patch>" doesn't mean to remove
    that patch, but only up to that patch.  "pop" alone removes the top
    patch, which is what's wanted.

  - Invoking "quilt pop" as "@QUILT@/pop" breaks gen_tempfile, which
    expects $0 to be something like "quilt pop", and REALLY doesn't like
    slashes.  Using the call formulation in bin/quilt.in solves this.

  - QUILT_COMMAND=delete is passed on to pop, which means pop picks up
    QUILT_DELETE_ARGS, which may not work.  Setting QUILT_COMMAND=""
    for the call to pop solves this.

Use a standard function "quilt_command" to invoke one quilt command from
another.
