[PATCH] Add Pascal/Delphi (.pas file) funcname pattern.

Finds classes, records, functions, procedures, and sections.  Most lines
need to start at the first column, or else there's no way to differentiate
a procedure's definition from its declaration.

Changes since v1:

- Tried using '\n' to separate the two parts of the regex, but it doesn't
  work.  Seems the lines are combined with AND instead of OR.  Also can't
  reduce the number of parens since only the part in parens is returned
  as the result string.
  
- Rename 'pas' type to 'pascal'

- Remove unnecessary 'type' match.
