debugcommands: print out the editor that was searched for (post shlexsplit) A user was in #mercurial and had the following settings in their hgrc: [ui] editor = C:\home\npp\notepad++.exe -multiInst -nosession After shlexsplit, the first argument was mangled into C:homenppnotepad++.exe, which was quite unlikely to exist. It took many back-and-forths to identify that adding " characters around the exe would fix the issue; we were thinking that it's because something was incorrectly *not* splitting and adding/moving the " characters fixed the split boundaries, but when testing afterward it appears that it's just mangled. I considered adding an informational if pycompat.iswindows and \ in the string about this issue, but was worried that might have too many false positives and did not do so at this time.
