Processing the file ip.1 below with
(woman-find-file "ip.1")
gets an error
Symbol's function definition is void: nil
with backtrace ip-backtrace.txt below.
The .IP line in ip.1 is bad in that the indentation arg is not a number
but I hoped woman would give some warning log and then continue
formatting the rest.
Putting the debugger on woman-parse-numeric-value suggests the two
skip-syntax-forward calls end up putting point in the middle of the .SH
request on the next line.
I wonder if woman-parse-numeric-value should confine itself to the
current line, per diff below.

* woman.el (woman-parse-numeric-value): Don't go past end of line for
a bad value or expression. Ensures point isn't moved part-way into a
request on the following line, such as
.IP "str" (notanumber)
.SH FOO
I struck this in the sdbm.3 man page
http://cpansearch.perl.org/src/RJBS/perl-5.16.0/ext/SDBM_File/sdbm/sdbm.3
which has a bad .IP line for the author. Maybe the quotes should be on
the whole string, but in any case it'd be good if woman didn't error out.
