ex_docmd.c: Save/restore winminheight/winminwidth. #5717

Browse Source 
Fix session load with winminheight/winminwidth >1.

Problem:  Vim temporarily sets winheight/winwidth to 1 while loading
          session. If user has his minimum window size set higher, this
          causes an error.
Solution: Temporarily set winminheight/winminwidth, and restore the
          original values (in the right order) when finishing session read.
          The order of the compound 'set' command is important, if it is
          wrong there will be an error.
