+# Expand variable starting with tilde (~)
+# We want to expand ~foo/... to /home/foo/... to avoid problems when
+# word-to-complete starting with a tilde is fed to commands and ending up
+# quoted instead of expanded.
+# Only the first portion of the variable from the tilde up to the first slash
+# (~../) is expanded. The remainder of the variable, containing for example
+# a dollar sign variable ($) or asterisk (*) is not expanded.
+# Example usage:
+#
+# $ v="~"; __expand_tilde_by_ref v; echo "$v"
+#
+# Example output:
+#
+# v output
+# -------- ----------------
+# ~ /home/user
+# ~foo/bar /home/foo/bar
+# ~foo/$HOME /home/foo/$HOME
+# ~foo/a b /home/foo/a b
