Change two HYPHEN-MINUSES (code 0x055, 2D) to an em-dash (\[em]), if one

(\[en] to one HYPHEN-MINUS, and an em-dash to two HYPHEN-MINUSES without
considering the space around it.

#####
Separate the sentences and subordinate clauses; each begins on a new
line. See man-pages(7) ("semantic newline") and "info groff".
The best procedure is to always start a new sentence on a new line,
at least, if you are typing on a computer.
Remember coding: Only one command ("sentence") on each (logical) line.
E-mail: Easier to quote exactly the relevant lines.
Generally: Easier to edit the sentence.
Patches: Less unaffected text.
The amount of space between sentences in the output can then be
controlled with the ".ss" request.

When you synchronize a compressed file between two computers, this option

the entire archive.

Normally, after a change is made to any file in the archive, the compression

previous version of the archive. In this case, rsync transfers the entire new
version of the archive to the remote computer.

that was changed.
