backslashes in pgindent

Luke, I have had to back out the removal of backslashes in the pgindent
awk script. Your patch was to remove them:

line1 !~ "^typedef" &&
line1 !~ "^extern[ ][ ]*\"C\"" &&
line1 !~ "=" &&
! line1 ~ "\)")
print "int pgindent_func_no_var_fix;";
line1 = line2;
}
--- 56,62 ----
line1 !~ "^typedef" &&
line1 !~ "^extern[ ][ ]*\"C\"" &&
line1 !~ "=" &&
! line1 ~ ")")
print "int pgindent_func_no_var_fix;";
line1 = line2;

I found that parentheses in gawk regular expressions require backslashes
so they are not treated as regex groupings:

$ echo '('|awk '$0 ~ /(/ {print $0}'
awk: cmd. line:1: fatal: Unmatched ( or \(: /(/
$ echo '('|awk '$0 ~ /\(/ {print $0}'
(

Now, it seems closing parentheses are OK because there is no open group,
but I think I should use backslashes there too:

$ echo ')'|awk '$0 ~ /)/ {print $0}'
)
$ echo ')'|awk '$0 ~ /\)/ {print $0}'

Does your awk produce different results? What version is it? Mine is GNU Awk
3.0.6.
