- inside `.Bl -column' phrases, punctuation is handled like normal |
|
text, e.g. `.Bl -column .It Fl x . Ta ...' should give "-x -." |
|
|
|
- inside `.Bl -column' phrases, TERMP_IGNDELIM handling by `Pf' |
|
is not safe, e.g. `.Bl -column .It Pf a b .' gives "ab." |
|
but should give "ab ." |
|
|
|
- set a meaningful default if no `Bl' list type is assigned |
|
|
|
- have a blank `It' head for `Bl -tag' not puke |
|
|
|
- prohibit `Nm' from having non-text HEAD children |
|
(e.g., NetBSD mDNSShared/dns-sd.1) |
|
(mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified) |
|
|
|
- When there is free text in the SYNOPSIS and that free text contains |
|
the .Nm macro, groff somehow understands to treat the .Nm as an in-line |
|
macro, while mandoc treats it as a block macro and breaks the line. |
|
No idea how the logic for distinguishing in-line and block instances |
|
should be, needs investigation. |

- The whatis(1) utility looks for whole words in Nm. |
|
If the file name of a page does not agree with the contents of any |
|
of its Nm macros (e.g. pool(9)), add the file name as an Nm entry |
|
to the mandoc.db as well, such that whatis(1) finds it. |
|
If there is a page with a file name that does not appear as a substring |
|
neither in Nm nor in Nd, the same fix would allow finding that page |
|
with apropos(1) using the file name as a key, as well. |

- .%T can have trailing punctuation. Currently, it puts the trailing |
|
punctuation into a trailing MDOC_TEXT element inside its own scope. |
|
That element should rather be outside its scope, such that the |
|
punctuation does not get underlines. This is not trivial to |
|
implement because .%T then needs some features of in_line_eoln() - |
|
slurp all arguments into one single text element - and one feature |
|
of in_line() - put trailing punctuation out of scope. |
|
Found in mount_nfs(8) and exports(5), search for "Appendix". |

- Trailing punctuation after .%T triggers EOS spacing, at least |

outside .Rs (eek!). Simply setting ARGSFL_DELIM for .%T is not |
