 MacOS 10.13.4, Xcode-9.3, current Macports and all the installed ports.

 Attempting to generate man pages from XML sources now result in Nroff tags
 being prefixed with one or more tabs. That in turn causes nroff to not
 format these pages properly. I just re-installed {libxslt}, and now its
 own man page is screwed up:

 Output of {{{man xsltproc}}}:

 Here's what the beginning of {{{/opt/local/share/man/man1/xsltproc.1}}}
 file looks like (observe how {{{.HP}}} tag does **not** begin at the first
 column of the line):

 In [https://github.com/OpenSC/OpenSC.git] package every tag in every man
 page is messed up this way (prefixed by one or more tabs or spaces, so the
 tag does not start at the beginning of the line, so roff ignores it).

 Attaching the page source and the generated result.

 Help is appreciated. *Yes, I know this port is not maintained.*
