patch 9.0.2118: [security]: avoid double-free in get_style_font_variants
Problem: [security]: avoid double-free
Solution: Only fee plain_font, when it is not the same as bold_font
When plain_font == bold_font and bold_font is not NULL, we may end up
trying to free bold_font again, which already has been freed a few lines
above.
So only free bold_font, when the condition gui.font_can_bold is true,
which means that bold_font is not pointing to plain_font (so it needs to
be freed separately).

README_ole.txt for version 9.0 of Vim: Vi IMproved. This archive contains gvim.exe with OLE interface. This version of gvim.exe can also load a number of interface dynamically (you can optionally install the .dll files for each interface). It is only for MS-Windows 95/98/ME/NT/2000/XP. Also see the README_bindos.txt, README_dos.txt and README.txt files. Be careful not to overwrite the OLE gvim.exe with the non-OLE gvim.exe when unpacking another binary archive! Check the output of ":version": Win32s - "MS-Windows 16/32 bit GUI version" Win32 - "MS-Windows 32 bit GUI version" Win32 with OLE - "MS-Windows 32 bit GUI version with OLE support" For further information, type this inside Vim: :help if_ole
