I had another go at trying to understand what was causing the problem. As it turned out, it is nothing to do with latex-suite itself, but with file type detection in vim. Using default settings (AFAIK), a file beginning with a \documentclass command is detected as LaTeX, while one beginning with a \chapter command is detected as plain TeX. This can be fixed by adding this line to ~/.vimrc:
let g:tex_flavor = "latex" It works as expected now. Apologies for originally reporting this as a possible bug in latex-suite. -- multifile project files not recognised as Latex https://launchpad.net/bugs/74986 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
