Convert a file pattern, as used by glob(), into a search pattern. The result can be used to match with a string that is a file name. E.g.

if filename =~ glob2regpat('Make*.mak')

This is equivalent to:

if filename =~ '^Make.*\.mak$'

When {string} is an empty string the result is "^$", match an empty string. Note that the result depends on the system. On MS-Windows a backslash usually means a path separator.

Can also be used as a method:

GetExpr()->glob2regpat()
