This change fixes the export of our FeynmanDiagrams.lyx example
files on the latest TeX Live 2016.
The IJMP(C|D).lyx examples compiled before the change but might as
well convert these instances of '\rm' also.
The changes were made with the help of the following command:
find ./ -iregex .*lyx -exec sed -i 's/\\rm /\\textrm /g' {} \;
and the resulting diff was confirmed manually.
This commit is consistent with 3cecd4d3.
Also MacOSX ReadMe files. Note that a few lib/doc files are
also "updated" because trailing spaces are removed, but their file
formats are the same because they were recently updated at 83672113.
I did "git checkout LFUNs.lyx" because this file is generated
automatically and has a special header.
dvipdfmx emits a lot of warnings and Koji suggests ps2pdf.
Thanks to Koji for the advice.
Note that on Debian, I installed the following packages
to be able to compile with ps2pdf:
fonts-takao-mincho
fonts-ipafont-nonfree-jisx0208
fonts-ipaexfont-mincho
