[UI] Do not include trailing EOL character when counting lines
- Adjust the counting of the number of lines of a file to match the
amount of rendered lines. This simply means that a file with the content
of `a\n` will be shown as having `1 line` rather than `2 lines`. This
matches with the amount of lines that are being rendered (the last empty
line is never rendered) and matches more with the expecation of the
user (a trailing EOL is a technical detail).
- In the case there's no EOL, the reason why it was counting
'incorrectly' was to show if there was a trailing EOL or not, but now
text is shown to tell the user this.
- Integration test added.
- Resolves Codeberg/Community#1612

// While this is a fairly short test, this exercises a number of

//
// - `.gitattributes` is empty, so `isDetectable.IsFalse()`,
// `isVendored.IsTrue()`, and `isDocumentation.IsTrue()` will be
// false for every file, because these are only true if an
// attribute is explicitly set.
//
// - There is `.dot.pas`, which would be considered Pascal source,
// but it is a dotfile (thus, `enry.IsDotFile()` applies), and as
// such, is not considered.
//
// - `some-file.xml` will be skipped because Enry considers XML
// configuration, and `enry.IsConfiguration()` will catch it.
//
// - `!isVendored.IsFalse()` evaluates to true, so
// `analyze.isVendor()` will be called on `cpplint.py`, which will
// be considered vendored, even though both the filename and
// contents would otherwise make it Python.
//
// - `!isDocumentation.IsFalse()` evaluates to true, so
// `enry.IsDocumentation()` will be called for `docs.md`, and will
// be considered documentation, thus, skipped.
//
// Thus, this exercises all of the conditions in the first big if
// that is supposed to filter out files early. With two short asserts!
