Subject: el/dot-emacs.el (Man-getpage-in-background): Don't try to split atoms.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/profile/commitdiff_plain/15e3b2e28dccbb5a6d4337b657320df2636e1e2f?hp=4b7a0fa89382f7d07d5b886712c4fb2eba8911b7

el/dot-emacs.el (Man-getpage-in-background): Don't try to split atoms.

In particular, the symbol `nil' isn't a string, so check for this
specially.  Conveniently, `nil' is exactly the right list.
