[latexrefman] Add section on \caption

[Vincent Belaïche]

Thank you Jim for this input.

Sorry to dwell on it, I still believe that « blank character » would
be better than « space », I already introduced this term in « Making
paragraph » with this added text which you had reviewed I think:

-----
The paragraph separator can be made of any sequence of at least one
blank line, amongst which at least one is not terminated by a comment. A
blank line is a line that is empty or made only of blank characters such
as space or tab. Comments in source code are started with a @code{%} and
span up to the end of line. In the following example the two columns are
identical:

@example
\documentclass[twocolumn]@{article@}
\begin@{document@}
First paragraph.

Second paragraph.
\newpage
First paragraph.

  % separator lines may contain blank characters.

Second paragraph.
\end@{document@}
@end example

-----

Would you object me to rephrase as (*…* = changed/added text) follows:

-----
Both commands cause @LaTeX{} to ignore *blanks* (that is, characters of
catcode at tie{}10 *such as space or tabulation*) after the end of the
----

I can do this in my next update to latex2e.tex which has lots of other
minor fixes.
