purge: abort with missing files avoiding problems with name-mangling fs

In a name mangling filesystem (e.g. a case insensitive one)
dirstate.walk() can yield filenames different from the ones
stored in the dirstate. This already confuses the status and
add commands, but with purge this may cause data loss.

To prevent this purge refuses to work if there are missing
files and has a 'force' option if the user knows it is safe.

Even with the force option purge checks if any of the missing
files is still available in the working dir: if so there
may be some problem with the underlying filesystem, so it
unconditionally aborts.

HGIGNORE(5)

NAME
----
hgignore - syntax for Mercurial ignore files

SYNOPSIS
--------

The Mercurial system uses a file called .hgignore in the root
directory of a repository to control its behavior when it finds files
that it is not currently managing.

DESCRIPTION
-----------

Mercurial ignores every unmanaged file that matches any pattern in an
ignore file.  The patterns in an ignore file do not apply to files
managed by Mercurial.  To control Mercurial's handling of files that
it manages, see the hg(1) man page.  Look for the "-I" and "-X"
options.

In addition, a Mercurial configuration file can point to a set of
per-user or global ignore files.  See the hgrc(5) man page for details
of how to configure these files.  Look for the "ignore" entry in the
"ui" section.

SYNTAX
------

An ignore file is a plain text file consisting of a list of patterns,
with one pattern per line.  Empty lines are skipped.  The "#"
character is treated as a comment character, and the "\" character is
treated as an escape character.

Mercurial supports several pattern syntaxes.  The default syntax used
is Python/Perl-style regular expressions.

To change the syntax used, use a line of the following form:

syntax: NAME

where NAME is one of the following:

regexp::
  Regular expression, Python/Perl syntax.
glob::
  Shell-style glob.

The chosen syntax stays in effect when parsing all patterns that
follow, until another syntax is selected.

Neither glob nor regexp patterns are rooted.  A glob-syntax pattern of
the form "*.c" will match a file ending in ".c" in any directory, and
a regexp pattern of the form "\.c$" will do the same.  To root a
regexp pattern, start it with "^".

EXAMPLE
-------

Here is an example ignore file.

  # use glob syntax.
  syntax: glob

  *.elc
  *.pyc
  *~
  .*.swp

  # switch to regexp syntax.
  syntax: regexp
  ^\.pc/
