doc.tmac contains the following lines:

.    ie (\n[doc-reg-dpr1] == 2) \
.      \" the `\%' prevents hyphenation on a dash (`-')
.      nop \%\*[doc-str-dpr]\&\c
.    el \{\
.      \" punctuation character
.      nop \f[\n[doc-curr-font]]\s[\n[doc-curr-size]u]\c
.      nop \)\*[doc-str-dpr]\f[]\s[0]\c
.    \}

The continuation at the beginning does not work as
expected since it ends with the comment, and the third
line is executed in any case. However, since the macro
file is normally processed by strip.sed before it is
installed, this problem disappears for the installed

Still, when using the macro file directly within the
source directory, \*[doc-str-dpr] is printed twice,
e.g. for .Xr with a comma as its third argument.

The issue can easily be fixed by using \{\ of course.
