Comment:
OK, I have found fixes for the vertical space issues both before and
after. In the sagetex.py file (I am not sure where the original is
supposed to be, I was fixing the version in `sage/local/lib/python2.6
/site-packages`).
Lines 77-78 should be
{{{
self.souttmp.write('\\newlabel{@sageinline' + str(counter) + '}{{%\n'
+
s.rstrip() + '}}\n')
}}}
I have removed four pairs of `{}` before the newline. It may be not the
proper place/way to do it, but the main idea is that these braces should
not appear on the last line of every command line listing in
`*.sagetex.sout`. This seems to fix the issue with extra space appearing
after sagecommandline, if the following text starts a new paragraph or a
theorem.
Line 145 should be
{{{
latex_string = r"\unskip\unskip\vspace{\sagecommandlineskip}" + "\n"
}}}
Two unskips eliminate the space before sagecommandline which was appearing
if the preceding line was "full." One unskip does not work, what is the
correct number of them I don't know, but I took the repetition idea from
`amsthm.sty` which contains
{{{
\ifhmode\unskip\unskip\par\fi
}}}
on line 140.
It is possible that `\ignorespaces` should be used somehow in the end of
blocks for even more robust behaviour.
Please include these fixes, for these spacing issues are really annoying
and it is somewhat non-trivial to figure out a workaround ;-)
