extract_call_seq(method)
Instance Public methods
Look for a 'call-seq' in the comment to override the normal
parameter handling. The :call-seq: is indented from the baseline. All
lines of the same indentation level and prefix are consumed.
For example, all of the following will be used as the :call-seq:
# :call-seq:
# ARGF.readlines(sep=$/) -> array
# ARGF.readlines(limit) -> array
# ARGF.readlines(sep, limit) -> array
#
# ARGF.to_a(sep=$/) -> arr
