[NTG-context] context --purgeall filename does not delete all temporary files

Hi, `context --purgeall filename` behaves differently from `context --purgeall`. `context --purgeall` deletes all files with the name `*-temp-*`. I would have thought that `context --purgeall filename` will delete all files with the name `\jobname-temp-*` but it does not. Is there a way to delete the `\jobname-temp-*` files without requiring an extra `context --purgeall` run? This is needed for deleting extra files by `t-filter` module or deleting extra files generated by automatic EPS to PDF conversion (with figures.cachepaths.prefix="\jobname-temp"), etc. Thanks, Aditya
