[PATCH 0/2] Provide virtual /dev/fd and /dev/{stdin,stdout,stderr} symlinks

[Johannes Schindelin <johannes.schindelin@gmx.de>]

These symbolic links are crucial e.g. to support process substitution (Bash's
very nice `<(SOME-COMMAND)` feature).

For various reasons, it is a bit cumbersome (or impossible) to generate these
symbolic links in all circumstances where Git for Windows wants to use its
close fork of the Cygwin runtime.

Therefore, let's just handle these symbolic links as implicit, virtual ones.

If there is appetite for it, I wonder whether we should do something similar
for `/dev/shm` and `/dev/mqueue`? Are these even still used in Cygwin?
