Looking through the existing strings "invalid ident line: %.*s" is 
already used by am so maybe we should reuse that (log.c also contains 
"invalid ident line: %s"). Is the translation correct?

#: builtin/am.c:1270
#, c-format
msgid "invalid ident line: %.*s"
msgstr "dòng thụt lề không hợp lệ: %.*s"
