Bug#944916: asymptote: asymptote.sty uses `\RequirePackage[space]{grffile}' which crashes

[Julian Gilbey <jdg@debian.org>]

Package: asymptote
Version: 2.60-1
Severity: important
Tags: patch

asymptote.sty has a line:

\RequirePackage[space]{grffile}

This requires the texlive-latex-extra package, which is not listed as
a dependency of asymptote, so without this being installed,
asymptote.sty will not run.

But actually.... the latest version of grffile.sty (for at least 2+
years), is just a stub file which loads graphicx.  And that is
compounded with the fact that the current version of grffile.sty is
broken: it cannot handle options (as found in texlive-latex-extra
2019.20191112-1) which causes asymptote to break too; that bug has
already been fixed upstream.

So since grffile no longer does anything, it would make sense to just
remove it from asymptote.sty, rather than introduce a dependency on
texlive-latex-extra.

Patch: delete line 199 of doc/asy-latex.dtx, which currently reads:

\RequirePackage[space]{grffile}

Best wishes,

   Julian
