"client_location = ../client " or a value with a trailing space is a
common setup mistake that surfaces much later as an unrelated error (a
missing client folder, a failed database login). Keys and values are now
trimmed of spaces, tabs and line endings when the ini is read, which
also covers the \r of files saved with Windows line endings. Spaces
inside a value are kept, and lines with an empty key are ignored.
Verified with a new unit test that loads an ini with padded keys and
values.
