#21 Fragment page number refs don't work in memoir class

[Anonymous]

The memoir LaTeX class uses different notation for references in the .aux file than vanilla LaTeX; they're something like

\newlabel{scrap1}{{\M@TitleReference {section_number}{Section Name}}}{page_number}}

Currently, nuweb assumes that there won't be any brackets inside the reference text; it just searches for the first closing bracket and then expects to find the page number immediately after. This clearly won't work with memoir. I've implemented a fix which counts brackets inside the reference section to find the page number:

4971,4977c4971,4987
< char dummy[50];
< if (3 == sscanf(aux_line, "\\newlabel{scrap%d}{%[^}]}{%d}",
< &scrap_number, dummy, &page_number)) {
< if (scrap_number < scraps)
< scrap_array(scrap_number).page = page_number;
< else

> }

Hopefully this can be cleaned up and implemented in an upcoming release.
