In fact the code dealing with RE in the editor is pretty bizzare.. I
rewrite would be necessary.

If you are building MC from source you can apply the attached patch.
 I am working on a patch to fix both this issue and the 1024 
characters line limit described in bug #19329. The final patch may 
or may not include the attached patch, so this is an interim 
solution.

When I used Command -> Find file and entered " $" (space and a 
dollar, meaning one space character at end of line, regular 
expression and case sensitivity is both checked), I find many lines 
in many files. However, when I enter one of the files, move to the 
start of the file and search for the same expression " $" using F7 
("regular expression" checkbox is checked, rest is unchecked), 
nothing is found ("Search string not found"). When I move to the 
line where the space was found by "Find file" the space at end of 
line is there.

To reproduce, file with lines like:

"a word "
"another "
"another "

may be used (without the quotation marks of course, the spaces at 
end of lines are important)
