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$' When {expr} is an empty string the result is "^$", 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()
