Summary: Script language not always recognised

Initial Comment:
LXR v0.9.8

In Lang.pm

  When trying to determine script language, test is for the beginning of the last part of a path, i.e. /interp. Matches if key of 'interpreters' is a prefix of the script interpreter name.
  Unhappily, prevents LXR-scripts from being recognised as they do not include a path.

  Test changed to match 'interpreters' name at end of string (without /)

  Potential problem: it is no longer a prefix test; are there cases where it matters?

!            if ($shebang =~ /$patt$/) {
---------------------- end of path --------------------------------

There is a related issue:

  Some files which are not scripts contain an emacs specification telling which language is used (e.g. the *.conf files in LXR). In that case, parse the spec to extract the language name and act just as if it was a script.

!        ($line =~ /^\#!\s*(\S+)/s)
!        || ($line =~ /^.*-[*]-.*?[ \t;]mode:[ \t]*(\w+).*-[*]-/);
--------------------------- end of patch ------------------------------
