Documentation:
Regexp specifying two-character tokens not to split when breaking lines.
Each token has one or more of the characters from `f90-break-delimiters'.
Note that if only one of the characters is from that variable,
then the presence of the token here allows a line-break before or
after the other character, where a break would not normally be
allowed. This minor issue currently only affects "(/" and "/)".
