applying various patterns to what we find there.
Instance attributes:
dir
directory from which files will be taken -- only used if
'allfiles' not supplied to constructor
files
list of filenames currently being built/filtered/manipulated
allfiles
complete list of files under consideration (ie. without any
filtering applied)

��z FileList.process_template_liner" r c C sl d}t ||||�}| �d|j � | jdkr4| �� | jD ],}|�|�r:| �d| � | j�|� d}q:|S )a� Select strings (presumably filenames) from 'self.files' that
match 'pattern', a Unix-style wildcard (glob) pattern. Patterns
are not quite the same as implemented by the 'fnmatch' module: '*'
and '?' match non-special characters, where "special" is platform-
dependent: slash on Unix; colon, slash, and backslash on
DOS/Windows; and colon on Mac OS.
If 'anchor' is true (the default), then the pattern match is more
stringent: "*.py" will match "foo.py" but not "foo/bar.py". If
'anchor' is false, both of these will match.
If 'prefix' is supplied, then only filenames starting with 'prefix'
(itself a pattern) and ending with 'pattern', with anything in between
them, will match. 'anchor' is ignored in this case.
If 'is_regex' is true, 'anchor' and 'prefix' are ignored, and
'pattern' is assumed to be either a string containing a regex or a
regex object -- no translation is done, the regex is just compiled
and used as-is.
Selected strings will be added to self.files.
Return True if files are found, False otherwise.
