Remove any common leading whitespace from every line in `text`.
This can be used to make triple-quoted strings line up with the left
edge of the display, while still presenting them in the source code
in indented form.
Note that tabs and spaces are both treated as whitespace, but they
are not equal: the lines " hello" and "\thello" are
considered to have no common leading whitespace. (This behaviour is
new in Python 2.5; older versions of this module incorrectly
expanded tabs before searching for common leading whitespace.)

@param count true iff it should count number of times each
line is executed
@param trace true iff it should print out each line that is
being counted
@param countfuncs true iff it should just output a list of
(filename, modulename, funcname,) for functions
that were called at least once; This overrides
`count' and `trace'
@param ignoremods a list of the names of modules to ignore
@param ignoredirs a list of the names of directories to ignore
all of the (recursive) contents of
@param infile file from which to read stored counts to be
added into the results
@param outfile file in which to write the results
@param timing true iff timing information be displayed
