If you ever need to use GNU make (still a popular tool) then you will be glad that you kept a policy of avoiding spaces in file names.

There are places in Makefiles where no amount of quoting will help you, and it simply cannot handle files with spaces.

Yeah, this is a problem with the tool that should be fixed, but my understanding is that it will never be fixed because of architectural reasons. And it's a very popular, useful, and most importantly, ubiquitous tool.

So this is another good reason to simply have a policy of banning filenames with spaces (and there are many more reasons).
