Until now @dircategory/@direntry entries were added only if
both TEXINFO_DIR_CATEGORY and TEXINFO_DIR_TITLE were set.
And the setting of TEXINFO_DIR_TITLE had to be careful to
provide exactly the right syntax.
This patch changes various things in this regard:
- Always generate a @dircategory/@direntry.
- Default TEXINFO_DIR_CATEGORY to "Misc".
- Use the document title by default if TEXINFO_DIR_DESC is missing.
- Rename TEXINFO_DIR_TITLE to TEXINFO_DIR_NAME.
- Use the filename by default when TEXINFO_DIR_NAME is missing.
- Try and make it harder to provide a direntry that does not
have the right format or refers to a different filename than
the one we're outputting to.
