[Rd] Potential cross-platform package building issue

I am using 32-bit R 3.1.2 on Windows 7.
I recently conducted an `R CMD check --as-cran` on a recently-developed
package and received only the 'New submission' note. Research on
StackOverflow and on R-devel suggested this could be ignored. I also used
devtools::build_win() and received no notes or warnings, other than the one
mentioned previously. Lastly, I conducted an `R CMD check` with the
development version of R. Further, I built the package locally with `R CMD
build` and `R CMD INSTALL --build` and everything worked as it should,
including the PDF manual.
Upon submission to CRAN, I was told that a warning was thrown:
This fails to make its manual:
* checking PDF version of manual ... WARNING
LaTeX errors when creating PDF version.
This typically indicates Rd problems.
LaTeX errors found:
! Missing $ inserted.
! Missing } inserted.
The line appears to be
I asked for assistance in resolving this issue as I could not replicate the
WARNING. Another user could replicate the warning on Ubuntu 12.04 but was
able to resolve the issue by removing the DOS end-of-line markers (^M or
Ctrl-M) from the .Rd file. Neither he nor I could find anything in the R
Extensions Manual that discussed removing end-of-line markers.

Is this an obscure cross platform issue? If so, I would have thought that
someone else would have already discovered this. If this is normal
behavior, is there a simple way to remove these end of line markers so I
can minimize WARNINGS from CRAN in the future?
