Subject: Fix: Missing postfix_expression DOT keywords in CTF grammar
X-Git-Tag: v1.3.0~45

Fix: Missing postfix_expression DOT keywords in CTF grammar

This would cause expressions of the form:

uint32_t a[stream.event.header.seq_len]

to fail to parse since two keywords (stream and event) are used in the
path.
