Hi Rob,</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
I started working on fold.c cleanup,</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
going through the code, and testing it out, i have a couple of questions.</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
<ol>
<li>gnu fold engulfs \n unconditionally i.e if there is a \n after the fold has happend that redundant \n does not make it to the output , that kind of makes sense but the posix spec only mentions carriage returns and only if the -b option is not specified.
(Note* That the current pending/fold outputs an extra new line.)</li><li>the current fold implementation has unfold capability , that i think should not be squeezed in fold (as of yet), my plan is to have unfold as a separate utility that uses infrastructure from fold if necessary, or at least make unfold as a config option,
please share your thoughts on this.</li><li>The tabstop thing is bit confusing for me, as the posix spec says <span>"Tab stops shall be at each column position</span><span> n such that n modulo 8 equals 1."</span> ( from this i understand that given the column the next column where the tab ends should
be a column whose modulo 8 returns 1 , kind of this pseudo code ? where start is the current column. (am i understanding it right ?)<br>

<span>int get_next_ts(int start)</span><br>
