Source and Doxifile file showing the problem

When we have a '(single quote) or " (double quote) in a normal Fortran comment (odd number of quotes), the Doxygen comment convert parser is broken.
When we have the source code (aa.f):
! A normal comment line with a ' (single quote) in it.

!> just a comment
!> \MY_ALIAS
SUBROUTINE TST
END

And the alias MY_ALIAS defined as MY_ALIAS=some text one would expect the text
"just a comment some text" in the output, but just the text "just a comment" is shown and the error messages in the console output (twice): aa.f:4: warning: Found unknown command `\MY_ALIAS'

Some investigation lead to the statement:
[^"'!\/\n\\#\\-]* { /* eat anything that is not " / or \n */
in commentcnv.l on line 264, here all characters are skipped till a quote (start of a string) in case of a non-comment line, but the normal Fortran comments are not recognized properly, only Doxygen Fortran comments are recognized.

In Fortran there is of course the problem that we have the ! comments, but in the fixed format also th C,c,*,! in column 1 (and excluding the ! in columns 6 as continuation character, but this is quite rare that this is used and error prone so we can forget this one in my opinion)

Changed version 'latest' to '1.8.2-SVN' so I can remove 'latest' as an option as it is a moving target.

PATCH: handle single quotes in normal Fortran comment

Comment handling for Fortran (fixed and free formatted) has been improved so that when there is a single quote (' or ") in normal comment this is not breaking the handling of aliases etc.

Confirmed. Should be fixed in the next subversion update.

Code is integrated and works as expected.
