Wording variations in descriptions of gucs.

Hello.

In guc.c many of the variables are described as "Set_s_ something"
as if the variable name is the omitted subject. A few seem being
wrongly written as "Set something" with the same intention.

Is it useful to unify them to the majority?

wal_level
> gettext_noop("Set the level of information written to the WAL."),

log_transaction_sample_rage
> gettext_noop("Set the fraction of transactions to log for new transactions."),

Though, recovery_target seems written as intended.

> gettext_noop("Set to 'immediate' to end recovery as soon as a consistent state is reached.

# rather it seems to be the detaied description..

regards.
