2022-06-09. "Inline" requests
Normally, troff inserts whitespace whenever it encounters a newline.
This is sometimes undesirable, especially when working with inline
formatting such as italics.
To avoid a word break before a request, put a \c at the end of the previous line. For example,
.ft I
un\c
.ft R
initialized
renders as:
uninitialized
Without the \c, it would render as:
un initialized
