# Map the path according to the given specification. The specification
 # controls the details of the mapping. The following special patterns are
 # recognized:
 #
 # * %p -- The complete path.
 # * %f -- The base file name of the path, with its file extension,
 # but without any directories.
 # * %n -- The file name of the path without its file extension.
 # * %d -- The directory list of the path.
 # * %x -- The file extension of the path. An empty string if there
 # is no extension.
 # * %X -- Everything *but* the file extension.
 # * %s -- The alternate file separator if defined, otherwise use
 # the standard file separator.
 # * %% -- A percent sign.
 #
 # The %d specifier can also have a numeric prefix (e.g. '%2d'). If the
 # number is positive, only return (up to) +n+ directories in the path,
 # starting from the left hand side. If +n+ is negative, return (up to)
 # |+n+| directories from the right hand side of the path.
 #
 # Examples:
 #
 # 'a/b/c/d/file.txt'.pathmap("%2d") => 'a/b'
 # 'a/b/c/d/file.txt'.pathmap("%-2d") => 'c/d'
 #
 # Also the %d, %p, %f, %n, %x, and %X operators can take a
 # pattern/replacement argument to perform simple string substitutions on a
 # particular part of the path. The pattern and replacement are separated
 # by a comma and are enclosed by curly braces. The replacement spec comes
 # after the % character but before the operator letter. (e.g.
 # "%{old,new}d"). Multiple replacement specs should be separated by
 # semi-colons (e.g. "%{old,new;src,bin}d").
 #
 # Regular expressions may be used for the pattern, and back refs may be
 # used in the replacement text. Curly braces, commas and semi-colons are
 # excluded from both the pattern and replacement text (let's keep parsing
 # reasonable).
 #
 # For example:
 #
 # "src/org/onestepback/proj/A.java".pathmap("%{^src,bin}X.class")
 #
 # returns:
 #
 # "bin/org/onestepback/proj/A.class"
 #
 # If the replacement text is '*', then a block may be provided to perform
 # some arbitrary calculation for the replacement.
 #
 # For example:
 #
 # "/path/to/file.TXT".pathmap("%X%{.*,*}x") { |ext|
 # ext.downcase
 # }
 #
 # Returns:
 #
 # "/path/to/file.txt"
 #
