[PATCHv2 0/8] Further filename completion improvements

[Andrew Burgess <aburgess@redhat.com>]

In V2:

  - Patches #1 and #2 are new in this iteration.  Patches #3 to #8 are
    the patches from V1 rebased onto these two new patches,

  - Patch #1 adds documentation for the formatting of filename
    arguments, this tries to explain the two diffent ways that GDB
    expects filename arguments to be formatted.

  - Patch #2 addresses the problem that Lancelot pointed out: some
    commands don't expect filename arguments to be quoted, or to
    contain escapes.  In this patch I split the filename completion in
    two so the two different filename argument formats are handled
    separately...

  - This clears the way for the rest of the series, which updates how
    completion works for those filename arguments that do accept
    quoting and escaping,

  - Patches #3 to #8 are in principle the same as in V1, but there
    were some changes after rebasing onto the new patch #2.
