Author: Deri James

[gropdf] Passing just "\" as a bookmark problem.

* src/devices/gropdf/gropdf: it ends up as a pdf string "(\)",
which is treated as an escaped bracket and the string is not
terminated! Solution is to embed the "\" in octal notation,
i.e. (\134).

[groff] 04/04: [man]: Fix Savannah #65729 (`de1 EE`).

[G. Branden Robinson]

gbranden pushed a commit to branch master
in repository groff.

commit f66cd8444ebd1531f81f69530ac7bc2f0c740a97
Author: G. Branden Robinson 
AuthorDate: Mon May 13 13:02:27 2024 -0500

[man]: Fix Savannah #65729 (`de1 EE`).

* tmac/an.tmac (EE): Define macro with `de1` request, not `de`.

Fixes .  Thanks to Bjarni Ingi
Gislason for the report.  Problem introduced by me in commit 15f8188656,
21 February 2022.

As a comment in the file notes:

Macros that are part of the external interface (TH, SH, P, etc.) or that
are called by traps of any kind must be defined with `de1` because they
might be called from a context where compatibility mode is enabled.  For
other macros, `de` suffices.

[groff] 03/04: [tmac]: Perform actual string comparisons.

[G. Branden Robinson]

gbranden pushed a commit to branch master
in repository groff.

commit 609d962fc02e517744ee4f68160648a78df3a020
Author: G. Branden Robinson 
AuthorDate: Sat May 11 09:54:35 2024 -0500

[tmac]: Perform actual string comparisons.

* tmac/fallbacks.tmac:
* tmac/troffrc-end: Bracket comparands to formatted output comparison
  operator with `\?` escape sequences to perform a more elementary
  string comparison on them (cf. a comparison of _formatted text_).
  This way they continue to perform their function even if the default
  font family has no coverage of Basic Latin (not a bizarre choice when
  considering potential rendering of documents using Devanagari or East
  Asian languages).  Unfortunately this means of comparing strings,
  while long documented in the GNU troff Manual, is neither idiomatic
  for *roff macro programmers nor portable to AT troff.  (The *roff
  language historically _lacks_ a string comparison operator.)  Each
  macro package will have to decide for itself whether it wants to have
  portability at the expense of requiring Basic Latin coverage (possibly
  switching fonts before and after a formatted output comparison for the
  sole purpose of obtaining it).  These two files are unconditionally
  loaded by the stock `troffrc`, and therefore must be dealt with in any
  case.

Fixes .  Thanks to Dave Kemper for
the report, and to him, Peter Schaffter, and Deri James for the
discussion.
