[vile] Recognizing '.t' files as perly

[Steven Lembark]

Odd thing: my #!.*perl and *.pm files show up with
"perlmode"; *.t files don't.

    define-majormode perlmode
    remove-submode perl cindent
    ~with define-submode perlmode
        preamble    "^#!.*perl"
        suffixes    "\\.(pm|t)$"
    ~endwith

Checking modes.doc, there aren't any examples of
dealing with multiple suffixes for a given mode
(examples show mixing a preamble with a single
suffix "\\.pl$"). I've also tried

    suffixes    "\\.\(pm|t\)$"

without any luck: I keep ending up in "confmode"
for my perl test code.

Using multiple suffixes lines:

    define-majormode perlmode
    remove-submode perl cindent
    ~with define-submode perlmode
        preamble    "^#!.*perl"
        suffixes    "\\.pm$"
        suffixes    "\\.t$"
    ~endwith

Gets me "perlmode" for *.pm and "perlmodemode" (no
typo) for *.t files.

Q: What is the correct syntax for attaching multiple
   suffixes to a single mode?

e.g.,, how much of the regex requires escaping to
have the metachar's handled properly?
