Possible but constrainful warkaround

When a protected area finishes with a closing bracket and line feed (LF):

{ \<LF>
    int a, b, c; \<LF>
    a = 1; \<LF>
    b = 2; \<LF>
    c = a + b; \<LF>
}<LF>

The closing bracket is removed and the protected body becomes:

{ \<LF>
    int a, b, c; \<LF>
    a = 1; \<LF>
    b = 2; \<LF>
    c = a + b; \<CR><LF>
<LF>

The only way to keep the closing bracket (last character of the body) is to add a CR like :

{ \<LF>
    int a, b, c; \<LF>
    a = 1; \<LF>
    b = 2; \<LF>
    c = a + b; \<CR><LF>
}<LF>

This bug is major because it modifies the protected area and removes character(s). The typical use case in C is a macro-like function:

#define DB_COMPARE_VALUES(value_1, value_2, result) \
/* Start of user code for DB_COMPARE_VALUES */ \
{ \
    if ((value_1) < (value_2)) \
    { \
        /* result is DB_LOWER if value 1 is lower than value 2 */ \
        (result) = DB_LOWER; \
    } \
    else if ((value_1) > (value_2)) \
    { \
        /* result is DB_HIGHER if value 1 is higher than value 2 */ \
        (result) = DB_HIGHER; \
    } \
    else \
    { \
        /* result is DB_EQUAL otherwise */ \
        (result) = DB_EQUAL; \
    } \
}
/* End of user code for DB_COMPARE_VALUES */
