When using #include or #includeIfPresent, it is easy to generate an
empty file name. For example,
#include "~OpenFOAM/missing-path/file"
On error, findEtcFile() returns an empty fileName. This was treated as
a relative name, which meant there was an attempt to open the parent directory
as a file. The resulting error message was confusing:
--> FOAM FATAL IO ERROR:
Attempt to put back onto bad stream
file: /CASE/PATH/system at line 1.
From function void Istream::putBack(const token&)
in file db/IOstreams/IOstreams/Istream.C at line 34.
