Typo: .substr in pmacros.texi is .substring in pmacros.scm

[Hans-Peter Nilsson <hans-peter dot nilsson at axis dot com>]

Please consider applying this patch.  It would IMHO be very useful
if .sym-built symbols were .pmacro-expanded, as I initially thought.
For example, a .pmacro could apply .sym on an argument and create
references to other, specialized .pmacro:s.  Currently this can be
accomplished only with the apparently frowned-upon "(.eval
(pmacro-expand '(.sym arg -something)))".  If you want, I guess I
can elaborate.

	* doc/pmacros.texi: Fix .substr typo to .substring.
	Mention that .sym expansions are not further expanded.
