By default, groff converts apostrophes in troff source to Unicode apostrophes. This is helpful and desirable when being used as a typesetter, since it makes the output much cleaner and more readable, but it is a problem in manual pages, since apostrophes are often used around shell commands and these should remain in their ASCII form for compatibility with the shell. Fortunately, the DocBook stylesheets contain a workaround for this case: they detect the special .g number register, which is set only when using groff, and they define a special macro for apostrophes based on whether or not it is set and use that macro to write out the proper character. As a result, the DocBook stylesheets handle all cases correctly automatically, whether the user is using groff or not, unlike our GNU_ROFF code. Additionally, this functionality was implemented in 2010. Since nobody is shipping security support for an operating system that old anymore, we can just safely assume that the user has upgraded their system in the past decade and remove the GNU_ROFF option and its corresponding stylesheet altogether. --- Documentation/Makefile | 8 -------- Documentation/manpage-quote-apos.xsl | 16 ---------------- 2 files changed, 24 deletions(-) delete mode 100644 Documentation/manpage-quote-apos.xsl diff --git a/Documentation/Makefile b/Documentation/Makefile index 536d9a5f3d..f3816772cf 100644 --- a/Documentation/Makefile +++ b/Documentation/Makefile @@ -177,14 +177,6 @@ MAN_BASE_URL = file://$(htmldir)/ endif XMLTO_EXTRA += -m manpage-base-url.xsl -# If your target system uses GNU groff, it may try to render -# apostrophes as a "pretty" apostrophe using unicode.
