[bug-gettext] msgcat error when merging fuzy entry with empty translation

[CircleCode]

given these 2 files:

----8<--- test1.pot ----------
#, fuzzy
msgid "foo"
msgstr "foo"
------------------------->8---

----8<--- test2.pot ----------
msgid "foo"
msgstr ""
------------------------->8---

msgcat does not ignore empty translation from test2:

$ msgcat test1.pot test2.pot
#, fuzzy
msgid "foo"
msgstr ""
"#-#-#-#-#  test1.pot  #-#-#-#-#\n"
"foo\n"
"#-#-#-#-#  test2.pot  #-#-#-#-#\n"

while it correctly ignore it if we remove the fuzzy comment from test1:

$ sed -i 's/#, fuzzy//' test1.pot && msgcat test1.pot test2.pot
msgid "foo"
msgstr "foo"

is this a feature or a bug?
