[with patch, positive review] remove spaces after continuation characters "\"

[mabshoff]

John H Palmieri reports:

In the section of the tutorial on 3d plotting,

<​http://sagemath.org/doc/html/tut/node22.html>

the continuation characters "\" all have spaces after them, which messes up cutting and pasting. Also in the section on Maxima,

<​http://sagemath.org/doc/html/tut/node54.html>

two of the backslashes have spaces after them (in the Mobius strip and the Klein bottle examples).

The same thing happens half a dozen times in "SAGE Constructions".

I've only searched the tutorial and the constructions documentation for this issue (by searching the files "tut.tex" and "const.tex"); I haven't looked at the rest of the documentation.

I did a regex search on all the tex documentation and all the docstrings for the pattern "
[\ ]+$" and replaced all the appropriate matches (filtered by eye). The changes are separated into patches for the docstrings and patches for the tex documentation. If this is accepted, both patches should be applied.

Patches look good to me. Positive review.

Cheers,
